The SiO2 content of silica bricks for glass kilns is 96-98%. Its density is 2.35-2.38g/cm3. It has high structural strength at high temperature, such as high load softening temperature (1640~1700℃) and low creep rate. After absorbing a small amount of alkali components in addition to very slight fusion corrosion, and doesn’t reduce the structural strength of the kiln roof.

Product characteristics of silica bricks for glass kiln

  1. High temperature volume stability.
  2. The glass liquid is slightly polluted.
  3. Chemical corrosion resistance.
  4. Small bulk density, which can reduce the weight of the furnace body.
